Referring again to Figure 1A, after half tone 100 is provided, then, half tone 100 is configured on light-passing board 200.Then, site material 300 is made to be distributed on the barrier film 120 of half tone 100.Please refer to Figure 1B, the site material 300 of part passes through first through hole 122, and on light-passing board 200, form multiple first site 222.In the present embodiment, the site material 300 of part is by first through while hole 122, and the site material 300 of another part by second through hole 126, and can form multiple second site 226 on light-passing board 200.After (sclerosis) is solidified in the first site 222 and the second site 226, just tentatively can complete the light guide plate 200 ' of the present embodiment.
The light guide plate 200' of the present embodiment can with obtained by above-mentioned half tone 100 and method for making.Fig. 5 be the light guide plate of Figure 1B on look enlarged diagram.Please refer to Figure 1B and Fig. 5, light guide plate 200 ' comprise exiting surface 210 (with reference to Figure 1B), relative to exiting surface 210 bottom surface 220, connect exiting surface 210 and bottom surface 220 incidence surface 230 and utilize half tone 100 (with reference to Figure 1B) made multiple first sites 222 on bottom surface 220.First site 222 lays respectively on the circumference Cp' of the multiple circle of reference C ' on bottom surface 220.Or rather, the geometric center of the first site 222 is positioned on the circumference Cp' of circle of reference C '.The center of circle Cc' of multiple circle of reference C ' is array distribution.The center of circle Cc ' of each circle of reference C ' is reference vector V1 ' to the vector of the geometric center of the first corresponding site 222.In the present embodiment, multiple circle of reference C, radius in fact can be identical.Circle of reference C ', circumference Cp ', center of circle Cc ', reference vector V1, the outer rim of the first site 222 can be considered circle of reference C, circumference Cp, center of circle Cc, reference vector V1, first through the edge (with reference to Fig. 2) in hole 122 along the orthogonal projection of opposite direction on bottom surface 220 of direction K3.In the present embodiment, the dimension D 1 ' (i.e. the breadth extreme of the first site 222) of each the first site 222 can be less than 10 times of mesh 112 width R2 (with reference to Fig. 2) with the summation of 6.4 times of netting twine 110 wire diameter R1 (with reference to Fig. 3).
It should be noted that reference vector V1 ' has part at least towards different directions.In other words, the first site 222 is in non-periodic distribution.First site 222 in manufacturing process may by periodic distribution anastomose 114 destroy, but because the Position Design of the first site 222 itself is namely in non-periodic distribution, therefore destroy by the anastomose 114 of periodic distribution the first site 222 not easily in periodic distribution.Thus, in the prior art, the generation probability of the repeatedly line caused by the first site 222 be destroyed just can be lowered, and then makes the good optical properties of light guide plate 200 '.
In addition, in the present embodiment, due to anastomose 114 tool periodicity in a plurality of directions, if each circle of reference C, radius be less than or equal to the wire diameter R1 of each netting twine 110 and the half of each mesh 112 width R2 summation, then the first site 222 of destroying by anastomose 114 more not easily form periodic distribution, and then the probability that in prior art, repeatedly line produces can be lowered further.
In the present embodiment, light guide plate 200' also comprises multiple second site 226.First site 222 is between incidence surface 230 and the second site 226.The dimension D 2 ' (i.e. the minimum widith of each the second site 226) of each the second site 226 is greater than the dimension D 1 ' (i.e. the breadth extreme of each the first site 222) of each the first site 222.The dimension D 2 ' of each the second site 226 be greater than 10 times of the width R2 (with reference to Fig. 2) of mesh 112 with the summation of 6.4 times of the wire diameter R1 (with reference to Fig. 3) of netting twine 110.
In addition, in the present embodiment, the dimension D 1 ' of the first site 222 and the dimension D 2 ' of the second site 226 little by little can increase along with away from incidence surface 230.Because the amount from incidence surface 230 incident ray can reduce along with away from incidence surface 230, therefore when the dimension D 1 ' of the first site 222 and the dimension D 2 ' of the second site 226 are along with when increasing away from incidence surface 230, the optical characteristics of light guide plate 200 ', such as light-emitting uniformity, can promote further.Second site 226 of the present embodiment can the distribution in array.Furthermore, the geometric center of the second site 226 can present the array in same cycle with the center of circle Cc' of circle of reference C ' and distributes.In the present embodiment, the geometric center of the second site 226 can overlap with the center of circle Cc' of circle of reference C '.
Due to the distance between the center of circle Cc ' that the first site 222 and array distribute very little (being namely less than or equal to the wire diameter R1 of each netting twine 110 and the half of each mesh 112 width R2 summation) and the second site 226 distribute in array, therefore, on macroscopic, the distribution of the site (comprising the first site 222 and the second site 226) in light guide plate 200 is still similar to array type and distributes.But as above-mentioned reason, the site of the light guide plate 200 of the present embodiment is divided and planted being similar to array type, still can play and reduce repeatedly line and produce the function of probability.
Fig. 6 is the light source module diagrammatic cross-section of one embodiment of the invention.Please refer to Fig. 6, light source module 1000 comprises light guide plate 200 and is configured at the other luminescence component 400 of light guide plate 200 incidence surface 230.The light P that luminescence component 400 sends enters in light guide plate 200 from the incidence surface 230 of light guide plate 200, and leaves light guide plate 200 from the exiting surface 210 of light guide plate 200.Light source module 1000 also can comprise reflector plate 300.The light P of part can be reflected back in light guide plate 200 by reflector plate 300, and then is used by light source module 1000.The light source module 1000 of the present embodiment adopts the light guide plate 200 of above-mentioned particular design, and therefore that the probability of line occurs repeatedly is low for light source module 1000, and has good optical characteristics.
In sum, in one embodiment of the invention light guide plate, the reference vector that the first site geometric center is pointed in the center of circle of circle of reference has part at least towards different directions, and namely the first site is non-periodic distribution.Because the Position Design of multiple first site itself is namely in non-periodic distribution, therefore in processing procedure part first site destroyed by the anastomose of periodic distribution not easily in periodic distribution.Thus, in the prior art, the repeatedly line caused by the first site be destroyed produces probability and just can be lowered, and on macroscopic, the network point distribution in light guide plate is still similar to array type distribution, and then makes the good optical properties of light guide plate.
In addition, in one embodiment of the invention light guide plate, when each can be less than or equal to the wire diameter of each netting twine and a half of each mesh width summation with reference to radius of a circle, the first site of destroying by the anastomose of periodic distribution more not easily in periodic distribution, and then the probability that repeatedly line produces caused by the first site be destroyed can be lowered further.
